Which Ipv6 first-hop security feature helps to minimize denial of service attacks?
A.
IPv6 Router Advertisement Guard
B.
IPv6 Destination Guard
C.
DHCPv6 Guard
D.
IPv6 MAC address filtering
IPv6 Destination Guard
Explanation:
The Destination Guard feature helps in minimizing denial-of-service (DoS) attacks. It performs address resolutions only for those addresses that are active on the link,and requires the FHS binding table to be populated with the help of the IPv6 snooping feature.The feature enables the filtering of IPv6 traffic based on the destinationaddress, and blocks the NDP resolution for destination addresses that are not found in the binding table. By default, the policy drops traffic coming for an unknowndestination.
